Defined by production of IL-4, IL-5 and IL-13, Tc2 cells have been implicated in eosinophilic inflammation, airway hyperresponsiveness, mucus production, and chronic tissue inflammation in diseases including asthma, atopic dermatitis, and chronic rhinosinusitis. Emerging evidence suggests that Tc2 differentiation and function are shaped by alarmins, lipid mediators, hypoxia, and immunometabolic pathways involving glycolysis, fatty acid metabolism, and serotonin signalling. Compared with Th2 cells, Tc2 cells may exhibit distinct features including tissue adaptation, responsiveness to innate inflammatory cues, and relative corticosteroid resistance, suggesting non-redundant roles in sustaining chronic allergic inflammation. Current biologic therapies targeting Type 2 pathways likely influence Tc2 activity, although their effects on Tc2-driven inflammation remain unclear. Here, we review current understanding of Tc2 cell phenotype, differentiation, immunometabolic regulation, and effector functions, and summarise evidence linking Tc2 cells to allergic disease. We also highlight key unanswered questions regarding Tc2 lineage stability, tissue residency, antigen specificity, and therapeutic targeting. Together, these findings position Tc2 cells as emerging amplifiers of Type 2 immunity and potential contributors to treatment-resistant allergic disease.</p>","PeriodicalId":21493,"journal":{"name":"Scandinavian Journal of Immunology","volume":"104 3","pages":"e70146"},"PeriodicalIF":2.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13507951/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148819426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review delineates core concepts, key signalling nodes-emphasising the mechanistic target of rapamycin (mTOR) as an integrator of metabolic and immune signals-research and intervention strategies across metabolic and infectious diseases. Immune cells display metabolic plasticity: At rest, they depend mainly on mitochondrial oxidative phosphorylation, but swiftly shift to aerobic glycolysis upon activation to fuel effector functions. Pro-inflammatory subsets like Th1 cells and M1 macrophages lean heavily on glycolysis, whereas regulatory T cells favour fatty acid oxidation. Central pathways-glycolysis, the tricarboxylic acid (TCA) cycle, and amino acid metabolism-directly shape immune activation and inflammation via intermediates and regulatory enzymes. For example, succinate and itaconic acid are critical in inflammation control, while fatty acid and cholesterol metabolism dictate immune cell fate. In metabolic disorders such as obesity, diabetes, fatty liver disease, and atherosclerosis, immune metabolic reprogramming is the main driver of chronic low-grade inflammation and tissue injury. During infection, a metabolic tug-of-war ensues: Pathogens hijack host metabolism for survival, and the host counters by reprogramming its own metabolism. The idea of \"trained immunity\" highlights how metabolism-epigenetics crosstalk endows innate immunity with memory-like capacity. These insights inform therapeutic avenues-modulating metabolic pathways, nutritional interventions, and microbiome targeting-with wide potential. Challenges remain, including the complexity of in vivo networks and the need for precise interventions. Yet advances in single-cell multi-omics and metabolic flux analysis will deepen mechanistic understanding and enable breakthroughs in precision strategies.</p>","PeriodicalId":21493,"journal":{"name":"Scandinavian Journal of Immunology","volume":"104 2","pages":"e70141"},"PeriodicalIF":2.4,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13478702/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148761882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Viruses seeking latency must curtail this. Infected subjects would then have minimal immune system activation and remain healthy. However, a minority cannot prevent emergence of associated diseases. This conundrum remains despite our understanding (i) that interferon specifically suppresses the translation of viral mRNAs, but not host mRNAs, and (ii) that for the latent state only one latency-maintaining mRNA may be needed. Critical are mRNA loadings with purine (R) bases, relative to pyrimidine bases (Y). Base composition and structural studies have established the genome-wide potential of duplex DNA (hence transcripts thereof) to extruded stem-loops, the stems of which require parity between R and Y bases. Sometimes conflicting with coding demands, parity-violations (R > Y) decrease this potential in exons (and hence in mRNAs). Thus, one mRNA (EBNA-1) of the Epstein-Barr virus (EBV) is successful in not alerting hosts to immune awareness. However, Y-rich transcripts might occasionally arise in the highly polymorphic 'junk DNA', long known as pervasively transcribed. Thus, within a minor subset of the infected population, some may, by chance, have randomly mutated to create pyrimidine-loaded regions that would form forbidden double-stranded RNA duplexes with purine-loaded EBNA-1 mRNAs. Thus, immune systems would awaken. Other viruses, differing in types/extents of latency, have evolved different survival strategies. Thus, mRNAs of the extremely latent human T cell leukaemia virus (HTLV1) are Y-loaded (Y > R), but a single latency transcript is highly R-loaded. In contrast, most mRNAs of less extremely latent retrovirus (HIV1) are expressed with R > Y.</p>","PeriodicalId":21493,"journal":{"name":"Scandinavian Journal of Immunology","volume":"104 1","pages":"e70135"},"PeriodicalIF":2.4,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13311203/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148346184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the effects of Bacterial Membrane Vesicles (BMVs) from these bacteria on macrophages infected with L. amazonensis. BMVs were characterised by Nanoparticle Tracking Analysis (NTA), and their effects on macrophage viability, infection dynamics, and cytokine production were assessed. Macrophages infected with L. amazonensis and subsequently treated with BMVs exhibited reduced parasite burden and cell viability compared to infected controls. The production of cytokines was variably modulated depending on the vesicle source. TNF-α levels were higher in macrophages infected with L. amazonensis and treated with BMVs than in those infected with the parasite alone. Additionally, elevated levels of IL-1β were observed in co-cultures treated with P. aeruginosa membrane vesicles (POMVs), suggesting a stronger inflammatory profile than that induced by S. aureus extracellular vesicles (SEVs). In contrast, IL-4 and IL-6 levels were not significantly affected by either POMVs or SEVs. These results indicate that uninfected and L. amazonensis-infected macrophages respond distinctly to POMVs and SEVs, particularly through enhanced secretion of IL-1β and TNF-α.
